06:30am - Vector warns public to avoid downed power lines

Vector's crews have been working through the night to restore power and have reduced the number without power to 55,000, down from 79,000 last night. However it will be a few days until power and/or hot water is restored to all areas.

"As people start their days, it's important to stay well clear of any downed power lines or damaged electrical equipment. Treat power lines as live at all times," a Vector spokesperson says.

Vector's advice during ongoing outages

Please stay well clear of fallen power lines or damaged electrical equipment and treat them as live at all times.

Avoid possible damage to electrical appliances (in the unlikely event there is a power surge when the power is restored) by switching off appliances at the wall.

Where possible, make plans to stay with friends and family who have power, or make alternative accommodation arrangements.

Keep a torch and spare batteries handy and ensure that you have at least one telephone that does not rely on electricity for operation.

Ensure that an alternate fuel is always available for cooking.

05:45am - Fears for vulnerable after cold night without power

Auckland Emergency Management is urging people to check in on the vulnerable after a cold night in Auckland.

Temperatures dropped overnight as low as 6degC, and there are fears for those without power for heating.

"This is a time for us all to work together. Some people have been without power for almost 24 hours - this means cold water, food hygiene issues and a chilly night without heating," director John Dragicevich says.

"If you live next to someone who may be vulnerable, please pop over and check on them."

People that can't call on family or friends for help can call Auckland Emergency Management on 0800 22 22 00 for advice and assistance. If your life is at risk, phone 111.

05:30am - North Island in for more wind

MetService is warning residents of the upper North Island to prepare for another short, sharp spell of high winds on Thursday.

A severe weather watch has been issued for Northland and Auckland.

Metservice meteorologist Tom Adams says the blast will be "short lived", and is expected to be gone by 3am Friday.

A burst of heavy rain could also hit western areas of the South Island and many parts of the country will experience strong southwesterly winds, Mr Adams says.

"It's unfortunate changeable classic autumn weather."

This next wintry blast won't be as bad as the "chaos" of Tuesday, but with already damaged unsecured branches and power lines people should be wary of the potential of further damage or falling items, he says.
